When I try to delete particles, there is an error as follows:
version:Yade 20230129-7023~4e0a483~focal1
my code:
def deletParticle():
for bid in ParID:
x=O.bodies[bid].state.pos[0]
if (0.2<x<0.3):
for i in O.bodies[bid].intrs():
O.interactions.erase(i.id1,i.id2)
O.bodies.erase(bid)
ParID.remove(bid)
print(f'Particle {bid} is deleted.')
sp=pack.SpherePack()
sp.makeCloud([0,0,0],[0.5,0.5,0.5],num=10000)
ParID=[]
for c,r in sp:
ParID.append(O.bodies.append(sphere(c,r)))
O.engines=[
ForceResetter(),
InsertionSortCollider([Bo1_Sphere_Aabb()]),
InteractionLoop(
[Ig2_Sphere_Sphere_ScGeom()],
[Ip2_FrictMat_FrictMat_FrictPhys()],
[Law2_ScGeom_FrictPhys_CundallStrack()]
),
GlobalStiffnessTimeStepper(),
NewtonIntegrator(),
]
O.run(20)
deletParticle()
O.run()
